4 Claims. (Cl. 146-49) This invention relates to machines for reing partof this application, wherein like charmoving the outer surfaces of skinsof oranges or acters denote corresponding parts in the several the like,and may be generally defined as a citrous views, and in whichpeelscraper. Figure 1 illustrates a viewin side elevation of An object ofthe invention is to provide novel a citrous peel scraper embodying theinvention; J: means for scraping the part of the citrous fruit Figure 2illustrates a view in front elevation, containing oil, and for releasingthe fruit in order partly in section; and that it may be delivered to asqueezer or juicer. Figure 3 illustrates a view in elevation of the Afurther object of this invention is toprovide front of one of thescraping instrumentalities or novel means whereby a plurality ofscrapers may cups. 1. be operated in unison and successively receive theIn the drawing 5 and 6 1 denote standards or fruit to be treated andacting to successively disframe members having bearings 5 and 6 rechargethe fruit therefrom, as stated. spectively, in which a shaft 1 isrotatable and on It is an object of this invention furthermore which apulley-like wheel 8 is mounted to roto provide fruit embracinginstrumentalities rotate with the shaft. The wheel has a relatively 1|tatable in opposite directions while embracing wide face on which atpredetermined positions or engaging the fruit, the saidinstrumentalities the scrapers are mounted. Each mounting for being inthe nature of cups with abrading inner the scrapers comprises a plate 9which is secured surfaces which are effective to scrape the fruit; tothe rim of the Wheel in any appropriate manand it is furthermore anobject to provide novel ner, as by screws l0, and each plate has aper-'20 means whereby these instrumentalities are actutured lugs II at itsends, in which trunnions I2 ated or oscillatably mounted in pairs, thesaid of a bracket l3 are partially rotatable, so that instrumentalitiesbeing also rotatably driven the brackets may oscillate from positions inwhich during the movement in a certain zone and left they are shown atthe top of Fig. 2 to positions inactive as to their rotation duringtheir travel in which they are shown at the bottom of Fig. 2, as

' through another zone, so that when they are these two positionsrepresenting respectively the freed from rotation, they may separate todisscraper instrumentalities as embracing and opcharge the scrapings andthe fruit therefrom and erating on a fruit, and as releasing the fruitafter then move into cooperative relation to embrace it has beenscraped. Each bracket has a lug another fruit and operate to scrape thefruit i4 projecting inwardly from the side of the maso during itsmovement through another zone. chine to engage an adjusting screw I5 sothat It is a still further object of the invention to all of thebrackets may be set to move to postprovide novel means whereby pairs ofscraping tions where they are uniformly arranged. Each instrumentalitiesare automatically moved into bracket has bearings I6 and I! in spacedrelacooperative relation with each other to embrace tion to each other,in which a shaft [8 is rotat- 35 the fruit at a location where the fruitis delivered able, and a groove pulley I9 is mounted on the from atrough or chute, over which the fruit may shaft in the space between thebearings. Each travel; and the invention furthermore includes shaft hasa cup 20 on its inner end that rotates novel means for holding the fruiton the trough with the shaft and, as shown in Fig. 2, the cups or chuteduring the movement of the cups when coact as at the top of Fig. 2, whenthey are driven they are Out Of re y alinement t e in oppositedirections, to scrape the citrous peel. rou Chute delivering l Thegroove pulleys are engaged by a belt 2| which It is furthermore anobJect of the invention j breferably of the v type, although the toProvide novel means whereby the members inventor does not wish to belimited with respect embracing the fruit are rotated in opposite ditothis detail of operation z g i figi ig g i gxgg g gi z ififi gg At thebottom of the frame a relatively Wide time the fruit is received untilit is discharged. trough 22 1S prov'ldedfifor the reception s the Withthe foregoing and other objects in view, Scraipmg's a supenmposednarmwer T the invention consists in the details of construc- 23 plovlded2 recelve frult after 1t 1S tion, and in the arrangement and combinationscraped so that It y ve d to any suitof parts to be hereinafter morefully set forth able location, Such as a l and claimed. The innersurfaces of the cups 20 are rough- In describing the invention indetail, reference ened in any appropriate manner, as shown at 24,

will be had to the accompanying drawing formbut the inventor does notwish to be limited with 66 respect to the abrading inner surfaces of thecups.

Cup closing members 25 are anchored to the frame members 5 and 6 and, asshown in Fig. 1, the member on the side of the machine facing the readerhas its inner end attached to the standard or frame member 5 byfastenings 26. such as screws, rivets or the like, and the outer endthereof has a depending curved portion 21 which is situated in the lineof movement of the shaft bearings of the bracket as it is moved upwardlyfrom the position at the bottom of the machine, and the depending curvedportion is preferably yieldable to a limited extent and is effective toforce the brackets from the positions shown at the bottom of Fig. 2 tothe positions shown in the central portion of said figure at a time whena fruit is between the two coacting cups.

In order that fruit may not be dislodged from the delivering trough orchute 28 While the machine is being operated, except when cups are inposition to receive the fruit, a curved guard 29 is providedbetweeneach' of the pairs of cups and each guard may be supported by apost 30 or the like, carried by the member 8.

The belts 2| operate over the pulleys l9 while the cups are in ooactiverelation to scrape, but are disengaged therefrom where the belt passesover an idler 3| offset with relation to the pulley of the scraper whenthe scrapers reach the'lowermost positions as they are carried in acircle when assembled and operating. The belt also operates over anotherpulley 32 which is on a driven shaft 33 suitably journaled. The wheel 8is, of course, keyed to the shaft 1 and it is driven in any suitablemanner, preferably at a low R. P. M., and as this rotation occurs, theshafts of the pairs of cups will be rotated oppositely, as indicated bythe arrows in Fig. 2.
